China appears to have tamed a new outbreak of the coronavirus in Beijing, once again demonstrating its ability to quickly mobilise vast resources by testing nearly 2.5 million people in 11 days.

But, elsewhere in the world, cases were surging on Wednesday. Mexico, where testing rates have been low, also set a record with over 6,200 new cases, and reported 800 new deaths. In the US, increases over the past few days have jumped to near the level of the outbreak's previous peak in April. Several states have set single-day records, including Arizona, California, Mississippi, Nevada and Texas.
